SHINGLE-MAKING MACHINE.

This invention relates to a shingle making machine through which a sheetof shingle material passes for shearing the same into a plurality oflongitudinal strips and shearing the longitudinal strips into individualshingles.

The invention primarily concerns itself with novelmechanism foreffectively separating the strips of shingle material in both '10horizontal and vertical planes before they reach the transverse shearsthat sever the vention.

Figure-11 is a sectional view upon the line 111l of Figure 10.

Figure 12 is a plan view of the shingles 0 as sheared from the strips.Asshown on the drawings: Referring to the drawing, it will be ob servedthat the machine comprises a suitable frame 1 which is preferably castwith pairs of upwardly extending spaced arms 2, 3, 4 and 5 upon itssides: The pairs of spaced arms on one side of the frame are inalinement with thecorresponding arms on the other side of the frame. Thepairs of arms 7 form 'guideways or hearing slides for the bearing boxesfor the different shafts-of the machine. Below the bearing boxes aredepending lugs 6 in which adjustable screws ,7 are mounted for adjustingthe lower bear- '75 ing blocks as is well known in the art.

The bearing box slides formed by the arms 2 retain the bearings for theslitter shafts 8 and 9 as shown in detail in Figure 5. In referring tosaid figure it will be observed so that the shaft 8 is supported uponlower bearings 10 in contact with the screws 7, and the upper shaft 9 is'journalled in the separable bearings blocks. 11 and 12 the latter ofwhich fits over the lower shaft 8.35 The upper ends of each pair of arms2 are connected by a slotted transverse member 13 through which a screw14 extends. The lower end of each screw rests upon the bear; ings 11. Ashaft 15 is journalled in the transverse members 13 and is provided witha pair of worms 16 (Figure 10) which mesh with worm wheels 17 upon thescrews 14. Each shaft 15 is provided with a hand wheel 18 whereby theshaft may be rotated for rotating the worm wheels 17 for adjusting thescrews 14. The adjustment of the screws 14 will obviously adjust theshaft bearin s as is well known in the art. Spaced blocfis 19 are keyedupon the shafts 8 and 9, and cutting or slitting disks 20 are bolted orscrewed in any appropriate manner to the blocks 19 and are spaced apartthe width of the desired strip of shingle material.- The peripheries ofthe opposite disks upon the 5.

shafts 8 and 9 are in cooperative relation and are adapted for slittinga sheet of roofing into a plurality of strips, (three in the resentinstance) as the same is passed thereetween. The shafts 8 and 9 areinter-geared by the gears 21 and a sprocket 22 on the end of the shaft 8affords a means for rotating said shaft and imparting its rotation toshaft 9 through the gears 21.

The bearing box slides formed by the arms 3 retain the bearin s for apair of vertically spaced and para lel shafts 23 upon which-the drawrolls 24 are secured between which the strips of roofing are drawn. Thestrips of roofing which are denoted by the reference numerals 25 and 26and 27 descend in the form of a loop 28 (Figure 3) to provide slack, andthey then extend upwardly over a guide roll 29 to the strip separatingmechanism which is shown in detail in Figure 6.

In referring to Figure 6, it will be observed that a pair ofverticallyspaced and parallel shafts 30 and 31 are rotatably mountedinadjustable bearings 10, 11 and 12 which are mountedin the guidewaysformed by the arms 4 and which are adjusted by a worm shaft 15, screws14 and worm gear 17 as previously described in connection with theslitting mechanism. A pair of ooved rolls 32 are secured upon the sha30. These rolls are spaced apart so that the distance between theirrespective grooves will be equal to the width of, the

strips of roofing. A collar 33 is keyed upon the shaft 31 above eachroll32 and a stri separatin disk 34 is screwed upon each collar. eperipheries or outer margins of these disks are wedlgle shaped andextend into the grooves 35. the particular construction illustrated, theinner sides of the disks are fiat while the outer sides adjacent theperipheries are bevelled or wedge sha d. The peripheries of these disksexten into the grooves 35 of the rolls 32 and exert an outward wedgingaction against the two outer strips of roofing 25 and 27. Consequentlywhen the strips pass over the rolls 32, the disks34will rotate betweenthe strips and separate the outer strips 25 and 27 fromthe intermediatestrip 26, ac-' cording to the thickness of said disks. The

' shafts30 and 31 are geared together by suitable spur gears 36 one ofwhich is driven in a manner to be hereinafter set forth.

Beyond the strip separating mechanism is a pair of vertically spaced andstaggered rolls 37 and 38 which are suitably supported by the frame asbest shown in Fi re 3. These rolls are designed to temporari y se arateor art adjacent stri s of roofing. T e interm 'ate stri of roo g 26asses over the upper roll 3 while the strips 25 and 27 ad aeent saidintermediate strip pass under the roll 38. Consequently adjacent stripsof roofing are temporarily vertically separated and any bindin strandsor threads not severed by the 'tting mechanism or disks 32 are broken ortorn apart by this vertical separation.

arms 5 are provided with caps or sockets 45 through whichadjustablebearing screws 46 extend forengaging the tops of the bearings 4 4. Coilsprings 47 surround the screws between the bearings'44 and suitableabutments on said screws. The shafts 41 and 42 are intergeared 'b thespur gears 48' for simultaneous rotation. A sprocket wheel 49 is securedupon the shaft 41 and a sprocket chain 50 is trained-over said sprocketwheel and also over the aforementioned sprocket wheel 22 onthe slittershaft 8. v v

The draw rolls 39 and 40 feedthe roofing strips to the transverse shearswhich consist of a stationary shearin member 51 and a rotatable shearingInem r 52 keyed upon a shaft 53 which is suitably journalled in theframe of the machine. Y

The rotatable shearing member has a pluralityof shearing plates 54corresponding to the number of. strips of roofing removably secured tothe lower forward margin thereof as shown in .Figure 8 and adjacent eachshearing plate there is an additional shearing element 55 having abevelled cutting edge. The end of each shearing plate 54 opposite theelement 55 is correspondingly bevelled as indicated at 56; the bevellededges being parallel to each other.

The statlonary shears 51 comprise similar shearing plates 54 andelements 55 which are, however, reversely arranged with respect to therotatable shears as shown in Figure 2. The'outer face of the base of thestationary shears is of arcuate form as indicated at 57 in Figure 3 toprovide rotatable space for the rotatable member of the shears. Theseshears are designed to cut the shingles 58 shown in Figure 12.

The sheared shingles are adaptedto drop upon conveyor 'belts 59 whichconvey the same from the machine to any suitable point.

These conveyor belts are trained over pulpair of spaced pardrive shaft63 has a sprocket wheel .67 that drives the conveyor shaft 62 throu hthe sprocket chain 68 and the sprocket w eel 69 on the conveyor shaft.The far end of the shaft .53 carries a spur gear 70 (Figure 2) thatmeshes with an intermediate idler gear 71 which in turn drives a gear 72on the far end of the roll shaft 42.

The spur gear 48 on the near end of the roll shaft 41 meshes with'anidler gear 73 supported on the side of the machine frame. The ear 73drives the gear 36 on the shaft 30 t at carries the separating groovedrolls 32.

It will accordingly" be apparent that rotation of the drive shaft 63will operate the conveyors and rotate the transverse shear shaft 53which in turn through gears 70, 71 and 7 2 drives the draw rolls 39 and40. The lower roll shaft 41 drives the shafts 30 and 31 through theaforementioned gearing, and also the slitter shafts 8 and, 9 through thesprocket gearing and spur gears 21. The vertical separating or partingrolls 37 and 38 are freely rotatable and are not connected to thedriving mechanism.

From the foregoing, it will be apparent that a valuable improvement hasbeen made in connection with shingle machines of the type disclosed, inthat the strips of shingle material or roofing are effectively separatedand all connecting strands or threads are broken so that the, shearplates for one strip will not damage an adjacent strip.

1 am aware that many changes may be made and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and I therefore do not purposelimiting the patentgranted hereon, otherwise than necessitated by theprior art.

I claim as my invention:
